The interlace bug has been described as the card drawing the interlaced lines at the wrong place. So rather than drawing line X, followed by line X+1, it draws line X, followed by line X+10. Then it goes back and draws line X+2 followed by X+12. So the picture appears to "shake" up and down.
On mine, the shaking is so bad that it is aparent even when the nvidia logo comes up. It looked so scary that I quit X then and there. I had some flickering for text with the mga, but video looked great.

That's almost certainly what I'm seeing then. I get it a little bit with my 720p modeline, but it's nowhere near as pronounced as the 1080i modeline where it's almost unbearable.
I snagged my modelines from windows using PowerStrip. I haven't really tweaked them yet, I don't even know where to start.
I have another, related question:
When I use my 1080i modeline, xvidtune reports my resolution as 1920x1080. When I use my 720p or 480p modelines, instead of 1280x720 and 720x480, I get 1024x768 and 640x480 respectively.
When I was in windows using powerstrip, windows reported I was using the correct HDTV resolutions.
My question is: Why am I not getting standard CRT resolutions instead of HDTV resolutions on Linux? I'm using the modelines Powerstrip generated for windows when I had it working correctly.
Here are my modelines for those who are interested:

I'm currently using SuSE 9.2 with an Nvidia 6600GT card and the 6629 and everything is over DVI.
